ChillOut Motorsports Revolution Variable Speed Blower Fan - 4 Inch Diameter

The ChillOut Motorsports Revolution Variable Speed Blower Fan supplies high volumes of ducted air to your driver-cooling system or any setup that needs controlled airflow. Benefit from user-adjustable output and stable performance thanks to a custom conformal-coated control board driving a hand-built, soft-start brushless motor with computer-balanced blades.Discover the key features and benefits of this blower fan s design and construction:Variable-Speed Control (30 420 CFM):  Adjustable airflow from 30 CFM up to 420 CFM (4" option) using the integrated control electronics, which lets you match cooling demand to conditions, so you maintain comfort and system efficiency.Soft-Start Brushless Motor: The motor ramps up smoothly through a controlled start sequence and uses brushless architecture, which reduces current spikes and wear, so you protect wiring, extend service life and keep airflow dependable across long sessions.Conformal-Coated Control Board: The PCB is coated to shield against moisture and contaminants in harsh environments, which stabilises operation and helps prevent faults, so you keep the fan working consistently when temperatures and humidity fluctuate.Computer-Controlled Blade Balancing: Each impeller is balanced using precise instrumentation to minimise vibration at all speeds, which reduces noise and mechanical stress, so you get smooth airflow delivery and less fatigue on mounts and ducting.Carbon Fibre-Reinforced Thermoplastic Housing: The long-fibre composite construction provides high rigidity with low mass and strong impact resistance, which helps the fan shrug off knocks and heat, so you can mount it confidently in your competition car.Hand-Built Motor Assembly: The motor is assembled to tight tolerances with careful quality control, which ensures consistent electrical and mechanical characteristics, so you get repeatable airflow and reliable response to speed commands.Ducted-Air Optimisation: The blower is engineered for systems that move air through hose and duct runs, which supports efficient pressure and flow delivery, so you feed your cooling shirt or other equipment with steady, usable airflow.Use this blower to move controlled, ducted air into your cooling system and to tune that flow quickly for climate changes. The conformal coating, balanced impeller and composite housing suit busy installs where reliability and low maintenance matter. It is a smart addition to your cockpit-cooling setup, giving you adjustable airflow and robust construction that helps you stay focused and comfortable through demanding days.
